A study shows that a molecule produced by intestinal microbes can enter the brain and that its presence is also associated with altered brain connectivity.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

From the very moment of conception, calcium plays a pivotal role in fetal development. It rushes in as a wave around the egg to herald the sperm's arrival, binding to proteins that help kick off the whole developmental process. From this first influx, calcium continues to play a critical role in how the body's cells respond to outside signals. Calcium tells muscles to contract and nerves to release neurotransmitters, and is at least part of the signal that helps people form and retain memories.

Academia is not producing sufficient PhDs in the plant sciences to solve the crop production challenges facing a rapidly growing population.

Seven life scientists are among the 15 honorees for this year's National Academy of Sciences award ceremony set for today at the NAS's 135th annual meeting in Washington, D.C. The meeting also includes the induction of academy members elected last year (E.R. Silverman, The Scientist, 11[9]:1, April 28, 1997). The academy is presenting its highest honor, the Public Welfare Medal, to David A. Hamburg, president emeritus of the Carnegie Corp. of New York. Hamburg, 72, is being recognized "for his

The Scientist’s 5th installment of its annual competition attracted submissions from across the life science spectrum. Here are the best and brightest products of the year.

A GRADIENT OF PORE SIZES:Courtesy of Michael J. Sailorimparts a rainbow of colors to a porous silicon chip, one of a variety of new biosensor technologies in development around the world. The different colors correspond to different sized pores, ranging from a few nanometers to hundreds of nanometers in diameter. These pores help the device discriminate and detect proteins and other molecules based on their size.One morning in March 1995, the deadly nerve gas sarin wafted through the Tokyo subwa

The Wistar Institute in Philadelphia marks its 100th anniversary this year, but the mood at the nation's oldest independent biomedical research facility is hardly jubilant. The institute has been in turmoil for the last year, after the abrupt ouster of longtime director Hilary Koprowski, the famed virologist and immunologist who transformed Wistar from a dilapidated museum into a world-renowned research center. The commotion recently was stirred up further, when the 75-year-old Koprowski file
